Write an equation of the line that passes through the given point and is parallel to the given line.
saveliy_v [14]

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9

Step-by-step explanation:

Given equation of line is:

y = -2x+7

As the given line is in slope intercept form, the coefficient of x is the slope

Let m1 be the slope of given line

m_1 = -2

Let m2 be the slope of second line then

m_2= -2

The equation of line is given by:

y= m_2x+b

Putting the value of slope

y = -2x+b

Putting the point (4,1) in the equation

y = -2x+b\\1 = -2(4)+b\\1= -8+b\\b = 1+8\\b = 9

Putting the value of b in the equation

y = -2x+9

Hence,

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9
